Characteristic features of all Thermo-Flow® cooling tunnels

All-round insulation and accessibility

We have attached special importance to the energy-saving “all-round insulation” and to the hygienic design which facilitates cleaning. The patented design of the joint between the cooling tunnel hood and the floor section resembles a tongue and groove system, i.e. no hinges are needed to lift up the hood.


Tools are surplus to requirements 

All the hoods can be removed completely without using tools. Alternatively, it is possible to remove one individual hood and then simply slide the others along.


No need for long arms

Especially where belt widths exceed 1050 mm (42”), cleaning of both sides of the cooling tunnel is absolutely essential. With hoods that can be lifted on either side, SOLLICH cooling tunnels offer maximum accessibility. Of course, no tools are needed for this operation.

Good cooling is high-performance cooling

The maximum cooling effect can only be obtained with the optimum combination of correct temperature and a correspondingly high air speed. SOLLICH cooling tunnels achieve this by means of high-performance heat exchangers, large fans and accurately specified air ducts. Even in wide cooling tunnels, the air is conducted with such precision that the temperature varies no more than 1 ºC over the entire width of the tunnel. Optimum hygiene is also catered for; during production, fine-pored filters (filter class F5) retain particles as small as 1m. The cleaning process is facilitated by ease of access – once again, no tools are required.

Radial fans

Radial fans make sure an optimal air speed to cool center products and chocolate coating. The fans can be pivoted to allow better accessibility. 





The cooling module

  • Fully clad and insulated, no cold bridges
  • Optimum accessibility
  • Air filter and water separator are standard
  • Either with integrated cooling compressor or modulating system for cold water or glycol cooling
  • With automatic cooling capacity control
  • Air drying with electrical air heating or dehumidifier as an option

Belt tracking

Photo-pneumatic belt-tracking devices on both sides ensures that there is minimal lateral belt movement, thus maintaining product orientation and an enhanced belt life.





Discovering a smooth ride

Jolting belts have a detrimental effect on the cooling process. SOLLICH cooling tunnels have special space-saving belt drive stations requiring no maintenance; they are designed with hygiene in mind and fitted with shaft-mounted gear units. The result is that the products have a smooth ride. Additionally the devices are fitted with generously sized crumb trays.

Cleanliness at all times

As an option, all cooling tunnels may be fitted with an automatic washing station. These are particularly recommended when cooling sugar-based products and ensure that the cooling belt is kept constantly clean during production. Designed with a lifting lid, the washing station is easy to clean – as always, without tools.

The stainless steel option

Instead of the standard polyurethane hoods, all cooling tunnels can be fitted on request with robust “sandwich hoods”, plated inside and out with stainless steel. As an option, gas pressure cylinders can be installed to assist in the opening of these hoods, or alternatively the procedure can be automated by the use of spindle motors.

For machine widths in excess of 1300 mm, hoods which open outwards from the centre can be installed on request. These are 3 m long and have gas-pressure springs to facilitate opening from either side.
